Method for extracting active ingredients

Abstract

A method for extracting active ingredient(s) from a raw material to be extracted is provided. The method comprises the following steps: (1) mixing a raw material to be extracted with an aqueous solvent to provide a mixture; (2) conducting a homogenization to the mixture to obtain a first extract with active ingredient(s); and (3) conducting a high pressure homogenization to the first extract to obtain a second extract with active ingredient(s), wherein the homogenization in step (2) is conducted at a temperature ranging from normal temperature to 100° C.

Description

FIELD OF THE INVENTION

[0001] The present invention relates to a method for extracting an active ingredient from a raw material to be extracted, and particularly relates to a method for extracting an active ingredient from a raw material to be extracted by using a high pressure homogenization.BACKGROUND OF THE INVENTION

[0002] It is known that plants contain many active ingredients, which are beneficial for the human body, such as anthocyanidin in black tomatoes, serotonin in banana peels, and betalain, betaxanthin, polyphenol and flavonoid in Chenopodium formosanum, etc.

[0003] It is known that the active ingredients in plants can be extracted by way of such as the dipping method, expeller process, solvent extraction method, ultrasonic extraction method or supercritical extraction method. However, conventional methods are time-consuming, inefficient in extraction, and unable to be used in mass-production, and thus should be improved.SUMMARY OF THE INVENTION

[0004] In view of the deficienci...
